Philadelphia Zoo is thrilled to announce the birth of two threatened sloth bear cubs. The cubs were born January 2, 2023, at 3:53am and 4:16am to 10-year-old mom Kayla and 10-year-old dad Bhalu. This is the second successful birth of this species at the Zoo in the last four years, and marks the first successful pair of cubs of this species born in more than 30 years at the Zoo. Mom and cubs are doing well and the Zoo's animal team continues to monitor their health via camera in their behind-the-scenes den. Kayla is showing great maternal behavior and has been in constant physical contact with the infants since birth. The sex of the cubs has not yet been determined and names have not been chosen. They will NOT be visible to the public until April when mom decides it is time for them to venture out.
